[0037] The present application discloses an inner tank 1000, which will be described in detail below in conjunction with a dishwasher. It can be understood that the inner tank 1000 disclosed in the present application is not limited to application to dishwashers, but can also be applied to other devices having the inner tank 1000.

[0038] Combination Figures 1 to 5As shown, in some embodiments of the present application, the liner 1000 includes a middle frame 1100 and a back plate 1200, wherein the middle frame 1100 is provided with a flange 1150 located at the rear side, and the back plate 1200 needs to be connected to the flange 1150. A first groove 1310 is provided on one side of the back plate 1200 and the flange 1150 facing the other of the back plate 1200 and the flange 1150 (one side refers to one side of the one), and a second groove 1320 is provided on one side of the back plate 1200 and the flange 1150 facing the other of the back plate 1200 and the flange 1150 (one side refers to one side of the one), the second groove 1320 is arranged adjacent to the inside of the liner 1000 relative to the first groove 1310, the first groove 1310 is used to accommodate a sealant with fluidity, and the second groove 1320 is used to receive the sealant overflowing from the first groove 1310. By setting the first groove 1310 and the second groove 1320, the first groove 1310 is used to accommodate fluid sealant. The sealant is applied in the first groove 1310. When the middle frame 1100 and the back plate 1200 are assembled, the sealant is squeezed, and part of the sealant overflows from the first groove 1310 and is transferred to the second groove 1320. In this way, the overflowed sealant is prevented from being transferred to the interior of the inner tank 1000, thereby preventing the user from observing the overflowed sealant, thereby improving the texture of the product.

[0039] Specifically, the dishwasher has an inner tank 1000, the interior of the inner tank 1000 is formed as a receiving chamber 1400, the bowl basket and the spray arm of the dishwasher are set in the receiving chamber 1400, and the tableware is placed on the bowl basket. When the tableware needs to be washed, the water flow sprayed by the spray arm is sprayed to the tableware on the bowl basket, and then the water flow falls back to the bottom of the receiving chamber 1400 and is then circulated and drawn away and continued to be transported to the spray arm, so as to achieve cyclic cleaning of the tableware. The inner tank 1000 is generally a square structure, including a back plate 1200 and a middle frame 1100, the back plate 1200 is connected to the rear side of the middle frame 1100, so that the back plate 1200 and the middle frame 1100 are connected to jointly enclose the receiving chamber 1400, the front side of the middle frame 1100 is open and connected to the receiving chamber 1400, and the front side of the middle frame 1100 can be opened and closed by the door of the dishwasher. When the door of the dishwasher is opened, the tableware can be placed in the receiving chamber 1400, and when the door of the dishwasher is closed, the tableware can be washed. It can be understood that the orientations in this application are based on the normal placement of the dishwasher. The side of the dishwasher facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the right hand is the right, the side close to the ground is the bottom, and the side away from the ground is the top.

[0040] The connection scheme of the back plate 1200 and the middle frame 1100 is as follows: the middle frame 1100 has a flange 1150 located at the rear side of the middle frame 1100, for example, combined with Figure 1 and Figure 2 As shown, the middle frame 1100 includes a top plate 1110, a left side plate 1130 and a right side plate 1140, and the top plate 1110 is arranged on the top of the left side plate 1130 and the right side plate 1140. It can be that the top plate 1110, the left side plate 1130 and the right side plate 1140 are three parts respectively, which are connected together by connecting means. It can also be that the top plate 1110, the left side plate 1130 and the right side plate 1140 are bent from the same plate. The top plate 1110, the left side plate 1130 and the right side plate 1140 respectively have a flange 1150. It can be understood that the middle frame 1100 is not limited to the aforementioned examples. In some embodiments, in combination with Figure 3 and Figure 4 As shown, the middle frame 1100 may further include a bottom plate 1120 , which is disposed at the bottom of the left plate 1130 and the right plate 1140 , and the bottom plate 1120 also has a flange 1150 .

[0041] Combination Figure 5 As shown, the flange 1150 is arranged away from the interior of the inner liner 1000 (the accommodating chamber 1400). When assembling the back plate 1200 and the middle frame 1100, the back plate 1200 and the flange 1150 are abutted together and connected to each other. There are various connections between the back plate 1200 and the flange 1150. For example, the back plate 1200 and the flange 1150 are connected and fixed to each other by welding, riveting, screw connection, etc. Of course, as long as the back plate 1200 and the flange 1150 can be fixed together, the connection methods between the back plate 1200 and the flange 1150 will not be listed one by one here.

[0042] As mentioned above, the interior of the inner tank 1000 (the accommodating chamber 1400) will be used to clean the dishes. Therefore, for a water-related environment, it is necessary to perform a sealing treatment between the back plate 1200 and the flange 1150. In the related art, a glue (sealant) treatment is performed between the back plate 1200 and the flange 1150. However, when the back plate 1200 is connected to the flange 1150, the back plate 1200 and the flange 1150 jointly squeeze the sealant. Under the action of squeezing, part of the sealant leaks into the interior of the inner tank 1000 (the accommodating chamber 1400) through the junction of the back plate 1200 and the flange 1150. The sealant that leaks into the inner tank 1000 is in an irregular state, which will reduce the quality of the dishwasher. In particular, when the user sees the sealant through the interior of the inner tank 1000 (the accommodating chamber 1400), it will form a feeling of poor quality, which will bring bad effects. To this end, in this embodiment, a first groove 1310 and a second groove 1320 are provided to solve the problem.

[0043] A first groove 1310 is provided on one side of the back plate 1200 and the flange 1150 facing the other side of the back plate 1200 and the flange 1150 (one side refers to one side of the one), and a second groove 1320 is provided on one side of the back plate 1200 and the flange 1150 facing the other side of the back plate 1200 and the flange 1150 (one side refers to one side of the one). That is, the first groove 1310 and the second groove 1320 can be provided in various ways, which can be, combined with Figure 5 , Figure 6 and Figure 7 As shown, the side 1230 of the back plate 1200 facing the flange 1150 is provided with a first groove 1310, and the side 1230 of the back plate 1200 facing the flange 1150 is also provided with a second groove 1320; it can also be combined with Figure 8 As shown, a first groove 1310 is provided on a side 1230 of the back plate 1200 facing the flange 1150, and a second groove 1320 is provided on a side 1153 of the flange 1150 facing the back plate 1200; Fig. 9 As shown, the side 1153 of the flange 1150 facing the back plate 1200 is provided with a first groove 1310, and the side 1230 of the back plate 1200 facing the flange 1150 is provided with a second groove 1320; of course, there is also such a situation, combined with Fig.10 As shown, a first groove 1310 is provided on a side 1153 of the flange 1150 facing the back plate 1200 , and a second groove 1320 is also provided on a side 1153 of the flange 1150 facing the back plate 1200 .

[0044] Combination Figure 5As shown, relative to the first groove 1310, the second groove 1320 is closer to the interior of the inner tank 1000 (the accommodating chamber 1400). Before assembling the back panel 1200 and the middle frame 1100, a fluid sealant needs to be applied to the first groove 1310. It can be understood that the so-called fluid sealant is a sealant that is roughly in liquid form and is easy to change in shape. This makes it convenient to apply the sealant to the first groove 1310. The fluid sealant needs to undergo a solidification process to become a solid sealant, thereby forming a seal between the back panel 1200 and the flange 1150. In order for the sealant to form a good seal between the back plate 1200 and the flange 1150, a sufficient amount of the sealant needs to be applied in the first groove 1310. Then, when the back plate 1200 and the middle frame 1100 are assembled, the back plate 1200 and the flange 1150 are abutted together. The fluid sealant in the first groove 1310 will flow toward other positions between the back plate 1200 and the flange 1150 under the mutual extrusion of the back plate 1200 and the flange 1150, that is, part of the sealant will flow from the first groove In order to prevent the overflow of the sealant 1310, in the present embodiment, a second groove 1320 is provided at a position closer to the accommodating cavity 1400 relative to the first groove 1310, so that the overflowed sealant can enter the second groove 1320. The second groove 1320 forms a buffer for the overflowed sealant, thereby preventing the overflowed sealant from leaking into the accommodating cavity 1400 through the junction between the back plate 1200 and the flange 1150, thereby preventing irregular sealant from being formed in the accommodating cavity 1400, thereby improving the quality of the dishwasher.

[0045] As mentioned above, there are many ways to set the first groove 1310 and the second groove 1320. They can be set on the back plate 1200, on the flange 1150, or on both the back plate 1200 and the flange 1150. Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, in some embodiments of the present application, the first groove 1310 and the second groove 1320 are arranged on the side of one of the back plate 1200 and the flange 1150 facing the other, that is, the first groove 1310 and the second groove 1320 are only arranged on the side 1230 of the back plate 1200 facing the flange 1150, or the first groove 1310 and the second groove 1320 are only arranged on the side 1153 of the flange 1150 facing the back plate 1200, which facilitates the processing of the first groove 1310 and the second groove 1320.

[0046] Specifically, the back plate 1200 and the middle frame 1100 are two components, and the back plate 1200 and the middle frame 1100 have different shapes and / or sizes. If the first groove 1310 is set in one of the back plate 1200 and the flange 1150, and the second groove 1320 is set in the other of the back plate 1200 and the flange 1150, then the corresponding first groove 1310 and second groove 1320 need to be processed for the back plate 1200 and the flange 1150, respectively, so different equipment or construction is also required. Therefore, in this embodiment, the first groove 1310 and the second groove 1320 are set in the back plate 1200 or the flange 1150 at the same time, and only the same one needs to be processed, which is more convenient and quick. In particular, most of the middle frames 1100 and the back panels 1200 are sheet metal parts. It is sufficient to form two grooves (a first groove 1310 and a second groove 1320) by punching the back panel 1200 or to form two grooves (a first groove 1310 and a second groove 1320) by punching the flange 1150 of the middle frame 1100. There is no need to punch the flange 1150 of the middle frame 1100 and the back panel 1200 separately, which is beneficial to improving production efficiency.

[0047] Furthermore, combined with Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of the present application, the first groove 1310 and the second groove 1320 are arranged on the side 1230 of the back plate 1200 facing the flange 1150, so that the difficulty of production can be reduced. Specifically, when the first groove 1310 and the second groove 1320 are arranged on the flange 1150 of the middle frame 1100, the first groove 1310 and the second groove 1320 need to be processed on the flange 1150. The flange 1150 is much smaller than other positions of the middle frame 1100 and presents a certain angle. Therefore, if it is necessary to process the first groove 1310 and the second groove 1320 on the flange 1150, it is difficult. In particular, when the middle frame 1100 is a sheet metal part, the flange 1150 is formed by bending part of the sheet metal part. At this time, the flange 1150 and other positions of the middle frame 1100 are roughly vertical, and the difficulty of processing the first groove 1310 and the second groove 1320 on the flange 1150 is greatly increased.

[0048] For this reason, in the present embodiment, the first groove 1310 and the second groove 1320 are arranged on the back plate 1200. The back plate 1200 is generally a flat plate structure. Therefore, the first groove 1310 and the second groove 1320 can be more conveniently processed on the back plate 1200. Compared with processing the first groove 1310 and the second groove 1320 on the flange 1150, processing the first groove 1310 and the second groove 1320 on the back plate 1200 will greatly reduce the production difficulty, which is beneficial to improving production efficiency and reducing production costs.

[0049] Combination Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of the present application, the first groove 1310 and the second groove 1320 are designed to be arranged alternately, so that the sealant can be better filled in the first groove 1310.

[0050] Specifically, before assembling the back plate 1200 and the middle frame 1100 together, it is necessary to first apply a fluid sealant to the first groove 1310. During the application of the sealant, due to the construction process, the sealant may not be completely filled in the first groove 1310, for example, bubbles are formed at certain positions. In this embodiment, the first groove 1310 is designed to be arranged alternately with the second groove 1320, for example, the first groove 1310 and the second groove 1320 are alternately 1mm to 5mm, and the first groove 1310 and the second groove 1320 may be arranged alternately. The second grooves 1320 are spaced 1mm, 2mm, 3mm, 4mm or 5mm apart. In this way, when the back plate 1200 is fitted with the flange 1150, the sealant will first fill the first groove 1310, and then part of the sealant will overflow into the second groove 1320 through the position between the first groove 1310 and the second groove 1320 under the action of extrusion. By designing the first groove 1310 and the second groove 1320 to be alternate, it is more conducive to the sealant to fill the first groove 1310 first and then overflow, so as to improve the sealing effect. It can be understood that the so-called alternate arrangement is to alternately arrange along the extension direction of the junction of the back plate 1200 and the flange 1150, and the inside-outside direction (the inside refers to the inside of the inner liner 1000, and the outside refers to the outside of the inner liner 1000).

[0051] In order to facilitate the sealant overflowing from the first groove 1310 to overflow into the second groove 1320, Figure 5 and Figure 6 As shown, in some embodiments of the present application, an overflow gap 1330 is formed between the back plate 1200 and the flange 1150, and the overflow gap 1330 is arranged between the second groove 1320 and the first groove 1310, and the spacing of the overflow gap 1330 is L1. The position where the second groove 1320 is arranged is the inner side relative to the first groove 1310, then, the spacing between the portion 1210 of the back plate 1200 arranged on the outer side of the first groove 1310 and the portion 1151 of the flange 1150 arranged on the outer side of the first groove 1310 is L2, and L1 is satisfied to be greater than L2, so that it is more convenient to transfer the sealant overflowing from the first groove 1310 to the second groove 1320.

[0052] Specifically, when the back panel 1200 and the middle frame 1100 are assembled, the sealant in the first groove 1310 is squeezed by the back panel 1200 and the flange 1150, and the sealant in the first groove 1310 can overflow toward the inside of the first groove 1310 and toward the outside of the first groove 1310. Although the sealant in the first groove 1310 overflows toward the outside of the first groove 1310 and then overflows to be exposed outside the inner tank 1000, it will not be observed by the user (the dishwasher is wrapped in an outer shell), but it may cause other effects. For example, workers on the production line can easily touch the overflowed sealant. Therefore, in this embodiment, the portion 1220 of the back plate 1200 disposed between the second groove 1320 and the first groove 1310 and the portion 1152 of the flange 1150 disposed between the second groove 1320 and the first groove 1310 are alternately disposed to form a flow gap 1330, and the spacing L1 of the flow gap 1330 is larger than the spacing L2 between the portion 1210 of the back plate 1200 disposed outside the first groove 1310 and the portion 1151 of the flange 1150 disposed outside the first groove 1310, so that the sealant in the first groove 1310 is more likely to overflow into the second groove 1320 through the flow gap 1330, so that the sealant overflowing into the second groove 1320 also plays a sealing role after solidification. It can be understood that L2 can be 0, that is, the back plate 1200 and the flange 1150 are tightly fitted together.

[0053] Furthermore, in some embodiments of the present application, the flow gap 1330 extends along the extension direction of the second groove 1320 and the first groove 1310, that is, it extends roughly along the periphery of the back plate 1200, so that the sealant overflowing from various positions of the first groove 1310 can be directly transferred to the second groove 1320 through the flow gap 1330.

[0054] Specifically, the extension length of the flow gap 1330 is adapted to the extension length of the second groove 1320 and the first groove 1310. When assembling the back panel 1200 and the middle frame 1100, sealant is applied in the extension direction of the first groove 1310. Since the flow gap 1330 is adapted to the length of the first groove 1310, when assembling the back panel 1200 and the middle frame 1100, there is a need for sealant overflow in the extension direction of the first groove 1310. In this way, the sealant overflowing from different parts can be more evenly distributed into the second groove 1320 to prevent more sealant overflowing from local positions and less sealant overflowing from local positions, so that the overflowed sealant is distributed as evenly as possible in the second groove 1320 to form a better sealing effect.

[0055] Combination Figure 7As shown, in some embodiments of the present application, the distance between the two opposite sides of the first groove 1310 is L3, and the distance between the two opposite sides of the second groove 1320 is L4, satisfying the condition that L3 is greater than L4, so that the sealant of the first groove 1310 forms a larger sealing area.

[0056] Specifically, since the seal between the back panel 1200 and the middle frame 1100 is mainly formed by the sealant in the first groove 1310, in the present embodiment, the distance between the two opposite sides of the first groove 1310 is designed to be larger than the distance between the two opposite sides of the second groove 1320. Taking the first groove 1310 located on the back panel 1200 as an example, the sealing area formed between the sealant in the first groove 1310 and the flange 1150 is also larger, thereby ensuring the sealing effect. It is understandable that the connection between the back panel 1200 and the flange 1150 needs to fit tightly, and the distance between the two opposite sides of the second groove 1320 is designed to be relatively small, thereby ensuring the contact area between the back panel 1200 and the flange 1150, and ensuring the connection stability between the back panel 1200 and the flange 1150. It is understandable that the relative two sides are referenced to the inside and outside directions, such as Figure 7 Left and right directions shown.

[0057] Combination Figure 5 As shown, in some embodiments of the present application, the depth of the first groove 1310 is designed to be D1, and the depth of the second groove 1320 is designed to be D2, and the condition D1 is less than D2 needs to be satisfied. In this way, the overflowing sealant can be buffered while ensuring the effective contact area between the back panel 1200 and the flange 1150.

[0058] Specifically, as mentioned above, the connection between the back plate 1200 and the flange 1150 requires that the back plate 1200 and the flange 1150 are overlapped together and then connected by some connection means. Compared with the related art, an additional groove (the second groove 1320) is added in the present embodiment, which will reduce the contact area between the back plate 1200 and the flange 1150. The reduced contact area will affect the connection stability between the back plate 1200 and the flange 1150. In order to minimize the impact as much as possible, the depth D2 of the second groove 1320 is designed to be greater than the depth D1 of the first groove 1310. In this way, the distance L4 on the opposite sides of the second groove 1320 can be designed to be smaller than the distance L3 on the opposite sides of the first groove 1310. In this way, the contact area between the back plate 1200 and the flange 1150 can be maximized. The greater the depth D2 of the second groove 1320, the more effective it is in buffering the overflowed sealant, which is equivalent to having a greater depth D2 in the direction perpendicular to the flow direction of the overflowed sealant. In this way, buffering can be achieved more effectively.

[0059] Combination Figures 5 to 10As shown, in some embodiments of the present application, the cross-section of the first groove 1310 is designed to be an arc shape. When the back panel 1200 and the flange 1150 jointly extrude the sealant, the sealant will flow. The cross-section of the first groove 1310 is designed to be an arc shape. When the sealant overflows from the first groove 1310, it is more conducive to the sealant filling the first groove 1310, avoiding the formation of bubbles, thereby improving the sealing effect.

[0060] The present application also discloses a dishwasher, which includes the inner tank 1000 of the above embodiment. The inner tank 1000 of the dishwasher of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.
